Traffic lights for directing the traffic
The light signals are white lights or lights of different colours, emitted successively, continuously or intermittently, by one or more lighting bodies that compose a traffic light. The traffic lights that emit light signals for directing the traffic in intersections are installed obligatorily before the intersections, so that they are visible from a distance of at least 50 m. They may be repeated in the middle, above or on the other side of the intersections.
